CHAIR.

Application filed December 26, 1919;

To all whom it may concern:

Be it known that we, Gnoncn J. ZINKGRAF and ARTHUR WAGNER, citizens of the United States, residing at Sheboygan, in the county of Sheboygan and State of Wisconsin, have invented a certain new and useful Improvement in Chairs, of which the following is a specification.

This invention relates to improvements in chairs and has for its object to provlde a new and improved device of this description. Our invention has among other objects, to provide achair of any ofthe ordinary forms including rockmg chairs which can be shipped or stored in a dismantled or knock down condition so as to occupy a small space and which then can be easily assembled so as to be ready for use, and to also provide a construction for strengthening apermanently assembled chair that has been weakened by use and for making a strong, durable permanently assembled chair.

The invention is illustrated in the accompanying drawings, wherein Fig. 1 is a view showmg one form of chair embodying the invention;

Fig. 2 is a sectional view taken on line 22 of Fig. 1;

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1; w

Fig. 4; is a view of the front of the chair.

Like numerals refer to like parts throughout the several figures.

in manufacturing the knock down chair we make it up in sections and we may, for example, make up the back 1 and the rear legs 2 in one section. The front legs 8 may be connected together and form another section. The frame connecting the legs below the seat consisting of two pieces 4i and the cross pieces 5 may form another section and the seat 6 another section. The legs are connected together at the point at which the seat is attached, by the separable supporting pieces 7. The parts are held together by the removable arches, bows or connecting pieces 8 placed under the seat so as to be out of sight. These connecting pieces have bent or bowed ends 8 as illustrated in Fig. 2. hen it is desired to assemble the several sections of the chair they are brought together as shown in Fig. 1. The holding pieces 8 are then fastenedin position. We prefer to fasten the holding pieces to the sections of the chair by means of screws Serial No. 347,531.

so that they may be easily connected and disconnected. As illustrated in Fig. 2 the middle portions of the connecting pieces are connected with pieces 7 by means of screws 9. The bent ends are connected with pieces 10 and 11 by screws 12. Said connecting pieces are also connected with the legs 2 and 3 by means of screws 13 and with the seat 6 by means of screws 14. The pieces, 7, 10 and 11 are connected together in any desired manner as by mortise and tenon joints, dowel pins, screws, bolts or the like.

In the construction shown the pieces 7 are connected with the pieces 10 and 11 by dowel pins which fit into openings in the legs and the pieces. The piece 5 is also provided with te-nons or dowel pins which fit in openings in pieces 4. Pieces i are similarly provided with tenons or dowel pins which fit in the legs 2 and 3. In connecting the pieces 7 with the rear legs we prefer to use one dowel pin for each piece and also a bolt or screw, the leg at the back being preferably countersunk for the head thereof.

The present invention may be applied to a chair of any form including ordinary chairs, dining room chairs, rockingchairs and the like and these chairs may have Wood, pad or slip seats or upholstered constructions of any of the usual forms. The chairs are manufactured in sections and these sections can be stored or placed in cars for shipment, thereby taking up very little room and when these sections are delivered they can then be set up to form the complete chair, the connecting pieces 8 being connected to the parts by screws as shown in Fig. 2. l/Vhen the chair is finally assembled for use the stability of the chair may be further increased by fastening the parts 4 to the legs 2 and 3 by means of the pins or nails 15 which are shown in Fig. 3 partly driven in and ready to be driven into the tenons of parts l. It will be seen that by means of this construction the sections of the chair may be easily assembled or disassembled and that when disassembled they can be stored in a small space. When shipped disassembled many more chairs can be placed in a car and freight saved, thus permitting a cheaper rate to be secured and making it easier to secure the minimum weight on car load lots. The danger of breakage in shipping and handling the chairs is greatly reduced. The knock down feature is here. secured at little expense and the connecting pieces 8 may be made of rough green lumber if desired asthey are placedunderthe seat and are entirely out of sight when the chair is assembled.

We have described in detail a partly constructed chair embodying the invention but it is of course evident that the parts may be varied in many particulars and the invention appliedto chairs of various shapes and styleswithout departing from the invention as set.out-'in the claims hereto appended, and we therefore .do not limitourselves to the. particular construction shown.

rThis-same construction maybe. used for ch airsthat arenot knock down chairs, but :Which 1 are" permanently assembled.

, When it is desired to strengthen a permanently assembled. chair that has been weakened by use so as to make it strong and durable this can be 1 done by attaching the removable arches or'connecting piecesto the seat and 'associated'parts as herein shown. e c1aim:-

{1. A knock-down chair comprising a series of'sections one of which forms the seat of the chair, saidsections adapted when disassembled, tobe stored in a comparatively small space,

place where the seat is located, two bowed connecting pieces under the seat and removable fastening devices fastening said connecting pieces to said seat and said legs, and removable pieces connecting said legs so as to hold the several parts in assembled relation.

3. A knock-down chair comprising front and rear legs forming separated sections, a seat separate therefrom, removable pieces connecting said front and rear legs at the place where the scat'is located, two bowed connecting pieces under the seat extendin from the front to the rear of the chair and engaging the side pieces of the chair, the bowed ends engaging portions of the front and rear pieces, said connecting pieces being made of a different variety of wood from that forming the rest of the chair and removable fastening devices fastening said connecting pieces to said seat and said legs, and removable pieces connecting said legs so as to hold the several parts in assembled relation, and removable braces connecting said legs together intermediate the seat and their lower ends.

4. A chair comprising front and rear legs,

supporting pieces connecting said legs, a

seat and opposed bowed connecting ieces under the seat and connected with sai seat and supporting pieces so as to hold the parts in fixed relation.

In testimony whereof, we afiix our signatures in the presence of two witnesses this 17th day of December, 1919.
